Detailed Description

Ultra-low-power 16-bit microcontroller with 64KB FRAM, 2KB RAM, integrated LCD controller, 12-channel 12-bit ADC, multiple serial interfaces, and rich timers in an 80-pin LQFP. Runs up to 16MHz on the MSP430 CPUxV2 core. Operates from 1.8V to 3.6V with an internal oscillator. Ideal for battery-powered, LCD-driven devices that need fast, frequent nonvolatile writes and very low energy use.

Key Features

Core: MSP430 CPUxV2, 16-bit, up to 16MHz

Memory: 64KB FRAM (nonvolatile, fast writes), 2KB RAM

Peripherals: LCD driver, DMA, PWM, watchdog (WDT), brown-out detect/reset (BOR), power-on reset (POR)

Data converter: 12-bit ADC, 12 channels

Connectivity: I2C (listed as IC), SPI, UART/USART, IrDA, SCI

I/O: 63 configurable GPIOs

Clock: Internal oscillator; supports external crystals

Supply voltage: 1.8V to 3.6V

Temperature range: -40°C to +85°C (TA)

Package: 80-LQFP (12x12mm), surface-mount

Series: MSP430 FRAM

RoHS: RoHS3 compliant

Base product number: MSP430FR6977

Packaging option: Tape & Reel (TR)

Key Advantages

FRAM memory: Very fast writes, low power, and extremely high endurance versus Flash; no erase cycle needed

Lifecycle

Status: Active as of the latest available information; not flagged for discontinuation

Close equivalents and alternatives:

- MSP430FR6979: Same family, with larger FRAM and similar LCD/analog features

- MSP430FR6987 / MSP430FR6989: Same FRAM series with LCD driver; higher memory options and similar low-power profile

- MSP430FR6969 / MSP430FR6949: FRAM-based MSP430 with comparable peripherals; check pin count and LCD needs

- If you need ARM-based performance but still low power, consider TI MSP432 series (note: different core)
